Yesterday , I was at a customer`s site and when I tried to expand a filesystem , the following error appeared :
# chfs -a size=+10G /unixhood
0516-787 extendlv: Maximum allocation for logical volume hd11admin
In a nutshell ,That means the max number of allowable LV in that filesystems in 512 and when we try to increase/epand the filesystems it refuses because the number of LV would get beyond 512 ,so what we gonna do it to increase the maximum allowable LV for that filesystem .
We can do that in 2 ways CLI and smitty :
In the following explanation,I am going to set the max number of LV to 800 which may differ in you case!
# chlv -x 800 hd11admin
then expand the filesystem
smitty chlv –> Change a Logical Volume –> Press Enter –>LOGICAL VOLUME name — >Press F4
then chose the desired LV and a smitty menu like the following will appear :
